Rett syndrome is a progressive neurologic condition, affecting only girls and characterized by acquired microcephaly, dementia, seizures, autistic behavior, spontaneous hyperventilation, spasticity, hyperreflexia and a peculiar characteristic stereotypic movement disorder. A review of 35 EEGs (obtained over 0-8.5 years of follow-up) in 9 such patients(More)

is a coastal, nontimber forest resource ranging from North Carolina southwestward to Texas. The plant has special cultural and economic importance in coastal South Carolina, where the local Gullah community uses this resource in a form of coiled basketry. The plant is becoming increasingly unavailable to basket makers, however, because of habitat(More)
A 23-month-old boy with progressive muscle weakness and severe cardiomyopathy was found to have oil red O positive vacuoles predominantly in type 1 muscle fibers. Serum carnitine was normal, but muscle carnitine content was decreased. Both parents were clinically normal, but the muscle carnitine level was low in the father. Despite oral treatment with(More)
Recent electrophysiologic studies have focussed attention on the X-linked adrenoleukodystrophy (ALD) and its myeloneuropathic variant. No organized studies are, however, yet available on its relatively recently described neonatal variant. We conducted electroencephalographic, electroretinographic and evoked response studies in 2 patients with neonatal ALD.(More)
Examination of oxidative metabolism in mitochondria isolated from quadriceps skeletal muscle biopsy specimens of 4 patients with Kearns-Sayre syndrome has shown that the mitochondria were tightly coupled, with maximal respiratory rates depending on the presence of adenosine diphosphate (ADP), Ca2+, or uncoupler. The state 3 respiratory rates with(More)
Two brothers had nonobstructive hypertrophic cardiomyopathy, mental retardation, and vacuolar myopathy, and their mother died of cardiopathy at age 31. Seven families with this syndrome have been described; heredity appears to be X-linked dominant or autosomal dominant, with different expressivity in males and females. The biochemical cause of this(More)
Eleven electroencephalograms in 4 infants with urea-cycle disorders were reviewed. All infants had one or more abnormal EEGs. The abnormalities consisted mainly of multiareal spikes, spike-waves, or sharp-and-slow-wave activity. In addition, one patient, a term infant, exhibited exaggerated spindle-delta bursts. This infant, and also one other at a similar(More)
